Application July 6, 1954, Serial No. 441,197

8 Claims. (Cl. 30-47) This invention relates to a paperbook razor, andmore specifically, to a razor of the cheap disposable type. This type ofrazor is especially useful to people who are travelling and for somereasondo not carry a shaving kit. They find themselves on a Sunday orholiday in a place where the barber shops are closed and naturally donot wish to appear in public unshaved.

Persons caught in this situation do not ordinarily wish to pay the priceof a standard razor since they already have one, but are willing to paya small amount for an inexpensive disposable razor that will besatisfactory for one or more shaves.

Applicant has invented such a razor that, when folded, assumes theappearance of a conventional match book and when unfolded will assumethe proportions of a standard razor.

This improved razor may be purchased from stores and vending machines atany hour and may be conveniently carried in the pocket at all times foremergency use and subsequent disposal.

The primary object of this invention is to provide a paperbook,disposable razor for emergency use that is normally folded to theproportions of a match book with room for advertizing matter if desired,and one that may readily be unfolded to the size of a standard safetyrazor.

Another object is to provide a disposable razor that is furnished with anormal blade and a small supply of soap so that the article may be usedwherever water is available.

A further object is to provide a disposable razor that is simple andpractical in design and one that is made of cheap yet durable material.

Other objects and advantages will become apparent from the followingdescription.

In the drawings,

Fig. 1 is a perspective view of the razor in its unfolded, ready to use,form. 2

Fig. 2 is an exploded, perspective view of the component parts.

Fig. 3 is a top plan, with the blade partly broken away, of the razor.

Fig. 4 is a vertical, sectional view taken on the line 4-4 of Fig. 3.

Fig. 5 is a vertical, sectional view taken on the line 5-5 of Fig. 3.

Fig. 6 is a horizontal, sectional view taken on the line 6-6 of Fig. 1.

Fig. 7 is a perspective view of the razor in its folded position.

The numeral 10 designates the razor in general, the same comprising ablank which provides a housing 12 made of a single sheet of sturdy,water-repellent paper, cardboard or the like.

The inside surface of housing 12 is divided into vertical panels, 14,15, 16, 17 and 18 by score lines 14a, 15a, 16a and 17a. Intermediate thetop and bottom edges of the housing 12 are formed horizontal score lines18 and 19. All of the aforesaid score lines are provided to facilitiateassembly of the component parts of the razor and their subsequentfolding in to the positions shown in Figs. 1 and 7.

The panel 16 is provided, from score line 19 to the bottom of housing12, see Fig. 5, with a coating of soap 20 for use in lathering the faceof the user. The soap 20 is afiixed to the housing 12 by any suitableadhesive.

The razor proper, see Fig. 2, comprises a T-shaped mounting 21, having adepending shank 22, the mounting 21 being fixed to panel 16 from scoreline 18, to the top edge of housing 12, by any suitable adhesive. Themounting 21 may be made of plastic, metal or the like.

The mounting 21 is provided centrally with a short, upright extension24, having at one side a cam face 25. The lateral arm 26 of the mounting21 is provided at its ends with bearings 27.

The blade holder 28 is provided with studs'or pintles 30 for mounting inbearings 27, and a lug 31 to engage cam face 25. The holder 28 is cutout at 32 to ac commodate the extension 24.

The blade holder 28 is extended laterally as at 34,-

to provide a rectangular base 35 for the blade 36, the same being ofthin rectangular formation and having a slot 38.

The base 35 is centrally provided with an upstand ing rectangular lug39, proportioned to loosely fit the slot 38. Suitably adhesive may beused to aflix the lug I 39 in slot 38 of blade 36.

The base 35 is set back at 40, the thickness of blade 36 leavingshoulders 41 at each end to support the blade. The set back 40 serves toprovide a cavity 42 under the major portion of the blade 36 to preventclogging by soap and hair.

The rear edge of blade 36 abuts the shoulders 40a of set back 40, thesaid shoulders merging centrally and rearwardly of lug 39 into a reducedrelief area 44. As shown in Fig. 4, the base 35 has a rounded front edge45 substantially co-extensive with the cutting edge 45 of blade 36, saidedge being adapted to contact the face of the user.

The base 35, between rounded edge 46 and shoulders 40a and on oppositesides of lug 39, is provided with slots 47 and 48 adapted to co-act withcavity 42 to prevent clogging of the razor.

Fig. 2 indicates the order of assembly. The blade holder 28 is placed sothat pintles 30 are mounted in bearings 27 and lug 31 is snapped undercam face 25 to maintain the blade holder in the proper angular positionfor shaving as shown in Fig. l.

The panels 14 and 18 are coated with a special adhesive so that alongwith panels 15 and 17, they may be bent back to form the reinforcedtriangular handle 50 shown in Fig. 6. The panels 15 and 17 are bent awayfrom the razor for approximately and the panels 14 and 18 are thenfolded 120 so that they confront each other, with the edges 14b and 18babutting panel 16. The special adhesive causes panels 14 and 18 toadhere to each other, the same forming a central stifiening rib 49 forthe triangular handle 50.

In Fig. 7 is shown the folded, disposable razor. The blade holder 28 isfolded, as shown by dotted lines in Fig. 4, to a position parallel tothe inner face of housing 12. At this time the lug 31 snaps up past camface 25 to release blade holder 28.

From the foregoing, it is apparent that I have inventer a disposablerazor made of cheap material that is ingeniously designed to provide amatch book formation in folded condition. The razor will give theshaving service of a standard razor for a limited time, and in itscollapsed position, can readily be carried in Patented Sept. 6, 1955 thepocket so as to be ready for an emergency, since it takes up no moreroom than a match book.

I hereby reserve the right to make numerous changes in the size, shapeand arrangement of the parts Without departing from the spirit of theinvention and the scope of the appended claims.
